Our Mission

WorkoutGen is a free application designed and developed by Jean-Baptiste Thery. Jeremy Tellier, state-certified coach, validated its athletic consistency and filmed the 350+ exercise videos himself. The application is published and operated by JCODE.

No rigid plan or chatbot response: the WorkoutGen deterministic engine builds your program based on your goal, level, and availability. Jeremy Tellier, a state-certified coach, validates its athletic consistency, and machine learning calibrates this engine using the aggregated results of thousands of members.

4 goals, over 350 HD videos filmed by Jeremy, a full-screen vertical player with integrated set tracking, recent progress views, complete schedule management, 9 languages, and one-click installation. The application is free to use, and WorkoutGen Max adds the AI Coach, load suggestions, and advanced analytics. Behind every program is the expertise of a real human coach. Designed and developed in France.
